Exhibit:

Based on the network topology shown in the exhibit, which routers should be configured as route reflectors but also act as clients to other router reflectors to provide the most scalable solution?

A.
R1, R2, and R3

B.
R6, R7, and R12

C.
R3, R12, and R14

D.
R1, R2, R3, R4, and R5

E.
R4, R5, R6, R7, and R12

Explanation:

Key is which routers are route reflectors and clients at the same time
1. B R6, R7, and R12 are both clients and route reflectors Wrong Answer
1. A R1, R2, R3 would not route reflectors
2. C makes no sense, they are all the EBGP directly connect peers.
3. D no sense
4. E R4 and R5 are route reflectors but not clients as well. The best way to look at this is to look at each cluster individually to determine which should be route reflectors
